Last night I upgraded our company filesserver from debian entch to lenny. After a short test with my linux client and on my windows terminalserver, it seemed to work correctly. Well, this was quiet different the next morning.

Problem
The next day after the upgrade from debian etch to lenny, some guys were able to use all shares of the fileservers, others were not (those were a little angry).

Find cause
To debug the problem, add following two lines to your /etc/samba/smb.conf

log level = 3
log file = /tmp/samba.log

Now watch the logfile while you access the the share. This is my log:

…

== To solve ==

Now, Mr. Google said following after I searched for NT_STATUS_OBJECT_NAME_NOT_FOUND:
http://lists-archives.org/samba/30781-error-when-upgrading-to-samba-3-0-25b-nt_status_object_path_not_found.html

Well, in the last message of the thread, following can be read:
> A reboot in the Windows PCs was the solution.

Quit strange cause just one of the angry users didn’t shut down the pc over night. So I rebooted first my linux machine. Then all windows users had to reboot and some of them also had to manually delete all saved networkdrives (like k:) and restart the logon-script. The problem was vanished.

Not to forget

If the samba server was upgraded, always REBOOT the windows machines and manually DELETE and RECREATE the specific networkdrives.

If you want to change the language in LimeSurvey but nothing happens, you have to set the following configuration parameter (in config.php):

$translationmode = 1;

This strange “workaround” is required when your php installation has some bug (don’t ask me).

Much time has cost me to find this solution.

cat ~/.ssh/id_rsa.pub | ssh root@<REMOTESERVER> ‘mkdir ~/.ssh/ 2>/dev/null ; cat >> ~/.ssh/authorized_keys ; cat ~/.ssh/authorized_keys | uniq > ~/.ssh/authorized_keys.tmp ; mv ~/.ssh/authorized_keys.tmp ~/.ssh/authorized_keys’

If you get the error File “~/.ssh/id_rsa.pub” not found cancel with CTRL+C, execute command ssh-keygen and just hit enter to response questions. After that, call the first command again.

# vmware-config.pl
The VMware VmPerl Scripting API was not installed.  Errors encountered during
compilation and installation of the module can be found here:
/tmp/vmware-config0

Errors can be found in the log file:
‘/tmp/vmware-config0/control-only/make.log’

Solution
# apt-get update
# apt-get install libssl-dev

Following packages are now new installed on the system:
libc6-dev libssl-dev linux-kernel-headers zlib1g-dev

# vmware-config.pl

After vmware is now properly configured, you can savely remove those packages again (but - let it be).

Unfortunately a typo3 extension doesn’t exists yet.

If you wanna to someting like this:

for I in $(zgrep -H “from=<test@google.com>” /var/logs/*.gz 2>/dev/null)
do
  LOG_FILE=”`echo $I | cut -d ‘:’ -f 1`”
  DATETIME=”`echo $I | cut -d ‘:’ -f 2-4 | cut -d ‘ ‘ -f 1-3`”
  MAILID=”`echo $I | cut -d ‘:’ -f 5 | cut -d ‘ ‘ -f 2`”
  RECIPIENT_ADDR=”`zgrep $MAILID $LOG_FILE | grep ‘to=’ | cut -d ‘<’ -f 2 | cut -d ‘>’ -f 1`”
  echo “$DATETIME $RECIPIENT_ADDR”
done

You will notice sooner or later that this doesn’t work this way: The for-loop doesn’t only treat line-breaks as a new element but also space-characters. Well, how can that be solved, fast and easy. This way:

zgrep -H “from=<test@google.com>” /var/logs/*.gz 2>/dev/null | while read I
do
  LOG_FILE=”`echo $I | cut -d ‘:’ -f 1`”
  DATETIME=”`echo $I | cut -d ‘:’ -f 2-4 | cut -d ‘ ‘ -f 1-3`”
  MAILID=”`echo $I | cut -d ‘:’ -f 5 | cut -d ‘ ‘ -f 2`”
  RECIPIENT_ADDR=”`zgrep $MAILID $LOG_FILE | grep ‘to=’ | cut -d ‘<’ -f 2 | cut -d ‘>’ -f 1`”
  echo “$DATETIME $RECIPIENT_ADDR”
done

Solution

Open webmin, goto webminstats and open the module “Disk”. Then click on the link “configure module”. Scroll down until you see the list with all watched filesystems. Deactivate the list-entry “/proc/bus/usb” or simply delete it.

Error:

…
The path “/usr/src/linux/include” is a kernel header file directory, but it 

does not contain the file “linux/version.h” as expected. This can happen if 
the kernel has never been built, or if you have invoked the “make mrproper” 
command in your kernel directory. In any case, you may want to rebuild your 
kernel.

What is the location of the directory of C header files that match your running
kernel? [/usr/src/linux/include] 

Solution

Check if you have installed these packages (your kernel version may be different).

linux-headers-2.6-686
linux-headers-2.6.18-6
linux-headers-2.6.18-6-686
linux-image-2.6-686
linux-image-2.6.18-6-686
linux-kbuild-2.6.18
linux-kernel-headers

Solution

The problem was only solved after I disabled the cronjob, then deleted the module (first make backup of /etc/webmin/sysstats/modules/ !!). After I reinstalled the same version of Webminstats and copy back the backup, the error didn’t appear again (of corse you have to open the webminstats-page at least once for scanning an to reactivate the cronjob).

It seams that is problem started after I made an update of webmin and webminstats. But on other machines I did the same update without receiving errors.

If you wish to use Java in Opera, you have to install first the JRE, the Java Runtime Environment. In a Debian/Ubuntu system, just install the package “sun-java6-jre” (maybe you have to enable the “non-free” and “contrib” apt-get sources first).

Next configure Opera:
 Select the menu “Tools” -> “Preferences…”
 Goto Tab “Advanced” and select “Content”
 Activate checkbox “Enable Java”
 Klick on button “Java options…”. You can now select the path to Java JRE

In my case the Java Path was “/usr/lib/jvm/java-6-sun/jre/lib/i386″

Restart ist required and now Java should work in Opera.
